it would take me a lifetime to figure that one out! I never got past Algebra 3 & 4. I've been out of school for 13 years!

For those of you that don't know,
PI = Diameter / Radius

It used for the area of a circled:

Area = PI * r ^ 2

I guess my mind won't work in rounding with these series things. I'll have to add another dimension to my problem-solving, where every 8 could be 8.82...
It's aiight.

I did it another way and got 280,b y checking the diff between the numbers and the diff between those numbers and then adding back to reach the next no. Wonder if that made any sense !

It's not 3 cubed, stupid (that's your name, not an insult ) it's 3 to the power of pi. Not the same at all.
